Is quiet hours still active? If you go to Cortana Notebook ... Quiet Hours what does the Right Now switch say?

I don't have the exact same problem as you, but I do have a problem where Quiet Hours doesn't turn on at night. This seems to happen after a reboot or after Cortana installs an update. I have to go into Notebook ... Quiet Hours and toggle the Automatic Rules switch off and on, then it turns on. After doing that it keeps working for days, at least until another software update or reboot. I'm on .164 but this has been happening since build .0, and I've reported it in the Feedback tool.

I have a different kind of issue, maybe its not an issue, can be a "feature" LOL.
The problem is this: I use Quiet hours on a daily bases, and it works just fine, it is set to turn on at 2300 everyday, and to end at 0630 in the morning. So far (one month with the device) I have been pleased. However, all my notifications go off after 0700, after my alarm sets off, and after that I ussually have like 10-15 notifications of all kinds (mail, Win Central, MSPU, Drug reminder, FB Messenger, WhatsApp, Viber...)
Any1 else have this kinda behaviour?

I am having BOTH issues.
One where Quiet hours will either not turn on and/or turn off even though I have everyday checked. If I go into Cortana or the Quiet hours quick menu and turn off/on automatic settings...will work until I update anything.
The other where when Quiet hours decides to cooperate and work with my automatic rules, I will get ZERO notification sounds from SMS/WhatsApp/Email/Calendar until I unlock my phone...I will receive a phone call...and it will work after that..
